| 摘 要： | 采用RTK/水准确定两套坐标转换模型时,RTK测量的精度限制会降低模型精度.本文经推导论证,通过高程异常模型定位粗差,隔离粗差后可有效提高转换精度.最后通过工程算例验证了该方法的实用性.该技术可应用于不同坐标系坐标转换工作.

| Abstract: | When transformation model of coordinates is computed by RTK/level,the model precision could be deteriorated by the RTK's error.In this paper,the model precision was improved by localizing and insulating errors by model of height abnormity. |
